Question

The length of rectangle is thrice its breadth and its perimeter is 96 m, find the area of the rectangle?

Answer 1

ans. is given in the pic.

Answer 2

GIVEN :

• Let the Length be = 3x
• Now, Let the breadth be = x

TO FIND :

• Area of rectangle = ?

Step - by - step explaination :

=> LENGTH = 3x

=> BREADTH = x

=> Perimeter of rectangle = 2(l+b) = 96

$x = \frac{96}{8} = 12$

Now, here

→ Length = 36cm

→ Breadth = 12cm

AREA OF THE RECTANGLE =

=> LENGTH × BREADTH

=> 36 Cm × 12 Cm

=> 432 Cm²

Area of the rectangle = 432 Cm²
